You...

You are loud,
You are aggressive,
You hit rough and hard;
You startle.

But,

You bring calm,
Something one feels on knowing you a little,
Beyond that initial fear- which is, perhaps, your way of priming the senses for up coming joy,
Joy that pervades the soul
long after you have left.

You nourish the senses, you nourish the soul.

You are like a thunderstorm....
